<P>PROBLEM TO BE SOLVED: To solve the problem that, if a magnet rotor comprising such number of neodymium fan-shaped magnets as equivalent to the length of a stator yoke of a power generation motor is built in the power generation motor for rotation and power generation, and an inverter output 200v is made to flow through a delta connection of an input line of the power generation motor, a stator coil produces heat at the rotational speed outside the range of rotational speed of inverter frequency of 45-50 hz, and no rotation is available with a star connection, and further, a corner hits against a magnet pressing part of a power transmission plate and broken at the time when assembling the magnet, with assembly work being difficult because of falling. <P>SOLUTION: The number of fan-shaped magnets of the same poles in a line of magnet poles, being a base of fan-shaped magnet, relative to the length along rotational axis direction of a stator yoke of the power generation motor, is equivalent to that of the intervals between magnets of the same polarity where the thickness of the fan-shaped magnet to be arranged in rotational axis magnetic pole is arranged. The magnet rotor having been assembled at the intervals is a base. The power generation motor containing the rotor assembled based on the base exhibits low-speed rotation in a star connection while exhibits high-speed rotation in a delta connection. Changing between star and delta causes repetition of low speed and high speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
